The gas is then directed through the filter bags 12 in a manifold where the filtered air exits the baghouse.

A SumoBrain Solutions Company. For those requiring data output for recording and quality documentation purposes, a serial output cable and windows-based software program is optionally aztm. This invention relates to a composition of fibers and filter media made there from that provide for advantageous physical properties, especially for use with bag filters for a baghouse.

The filter media can have a thickness between 0. The nonwoven filter media of claim 16 that has two or more fibers blended with the inorganic fiber. The invention can also include filter media comprising: Therefore the filter bags need to be able to function in these operational temperatures. The first polymer can have a denier between 0.

asrm After the fifth and sixth cycles, the sample can withstand about 70 pounds of force. The following table illustrates the physical property benefit of the present invention when compared to a polyphenylene sulfide PPS fiber alone.

These heated particles can contact the filter bag and damage the bag rendered the filtering functionality ineffective. Most baghouses use long, cylindrical filter bags or tubes made of fabric as the filter medium.

FIELD OF THE INVENTION

We Accept Printable Order Form. The denier of the inorganic fiber can be between 0. Thanks for your patience. The invention can also include a nonwoven filter media comprising: With the above test parameter and tested filter media, the following results were achieved as shown in Tables 1 and 2: The MTG Digital Contact Thickness Gage accurately measures thickness of textiles, non-wovens, technical fabrics and many other materials.

Some of the industries that use bag houses to remove particulates from the air stream include garbage incinerators, coal plants or boilers, furnaces for melting metal and other materials, pharmaceutical production food manufacturing, chemical production and cement plants. Gas having particles enters the baghouse through hopper 10 of FIG. A sample of the blended fabric is cut into about a 2 inch by 6 inch piece in the machine direction.

With the above test parameter and tested filter media, the following results were achieved as shown in Tables 1 and DavisTextile Research Journal, Particulate in the gas stream are deposited on the filter bag. The inorganic fibers are blended with the polyphenylene sulfide fibers and supported by a scrim.

This model is NOT recommended when testing requires specific test pressure. In some applications, the gas includes particles that are heated such as in the coal, chemical, metal industries.

Filter Media – Southern Felt Company, Inc.

The filter media of claim 11 wherein said tensile test is preformed according to tensile test ASTM-D The weight of the filter media can be between 5. The nonwoven filter media of claim 1 wherein said polyphenylene sulfide fibers have a length of between 1 and 4 inches and a diameter of between 7 and 36 microns and said inorganic fibers have a length of between 1 and 4 inches and a diameter of between 5 and 30 microns.

The indicator is fitted on an 8 inch mm tall column to allow the indicator to be raised or lowered to accommodate different size test specimens. The fibers 14 with the larger diameter principally consist of polyphenylene sulfide and the fibers 16 with the smaller diameters are the inorganic fibers. In one embodiment, the filter media manufactured from the blended fibers has the physical property of total mass removal of about The denier of these fibers can be between 0.

Tank Pressure 5 Bar 4. In one embodiment, the polyphenylene sulfide fibers have a length of between 1 and 4 inches and a diameter of between 7 and 36 microns and said inorganic fibers have a length of between 1 and 4 inches and a diameter of between 5 and 20 microns.

Item Description Price Add.

A filter media comprising: From the acid resistance tensile test, it can be seen that after the first two cycles, the sample can withstand over Ids of force. The nonwoven filter media of claim 16 ast, a scrim supporting said first fibers and said inorganic fibers. Device used to purify air and keep cleanly the duct of hot air system or central air exchanger. No orders will ship and email response will be delayed during this time.
